To all :whom it may concern.

Be 1t*known that I, Eran. 'lronn, a citizen of the-United. States, residing at Hastings, in the county of Barry and State of Michigan, have im en-ted new and useful 1m rovements in Seal Loclred (lane, of which the following is a specification, reference being bad to the accompanying drawin s, forming a part thereof.

7 he purpose of this invention is to pro vide an improved construction of a can or like article, comprising a body member and cover member, having provisions for looking them together at closed position with the lock adapted to be secured by a seal.

It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings :=-Figure 1 is a side elevation of a can equipped according to this invention. Fig. 2 is a section at the line, 2 -2, on Fig. 1 on an enlarged scale. Fig. 3 is a detail section at the line, 3-3, on Fig. 2. Fig. 4 is a detail View similar to Fig. 3 showing a modification. Fig. 5 is aview similar to Fig. 3 showing another modification. Fig. 6 is a section at 6--6 on Fig. 5. Fig. 7 is a section at 7-4 on Fig. 5.

he drawings represent a can of the general character which will be recognized as a milk-shipping can comprising a body member, 1, and a cover member, 2, telescoped with the body, both being cylindrical at their telescoped position, the body memher having its upper end portion, 3, flaredou'twardly and the cover member which extends up in cylindrical form to the top having its top extended forming a flange, 4, which overhangs the flaring upper end of the. body member and is curved downward so as to extend outside of the periphery of said flared upper end of the body which is finished by an outwardlyeturncd wire bead, 5, which is engaged by an inwardly-turned wire head, 6, ofthe cover flange at closed position of the can members, asseen in Fig. 1. For the purpose of this invention. there is mounted upon the outer side of the body member, preferably in the angle between the cylindrical and the flared conical portion, and thereby partly upon the latter, a seallocking devicecomprisin a housing, 7, and a bolt, 8, mounted for sli ing in the housing, and positioned for thrusting its inner end through the flared portion 3, of

the body. member which is apertured in line with the i bolt slide-way to perm-it the bolt to be thus thrust through it for engagement with the inner member, which in the form shown, is the cover member of the can. For such engagement theeover member is provided with an upwardly-facing shoulder, 10, preferably produced by sinking a circumferen-tlally-extending groove or channel, 11, in the outer surface of said member which may be rolled in or otherwise formed by familiar methods of sheet metal Working. The housing, 7, isgcut away from side to side across the path, of the bolt at 7, toexposc and give access to the bolt for manipulating it for engagement or disengagement with the inner can member. 7

ills-illustrated, preferably the bolt, 8, is cylindrical and is provided with an annular boss, Bflwhichis stopped against the housingat the withdrawn position of the bolt and against the wal-l of the outer member of the can at the limit of its imithrust for locking. The transverse apertures, 7 ,;of the housing above mentioned, is preferably made as a notch or recess in Itheinner edge of the housing before it is applied to the can, the can completing the encoim-passment of the aperture when the housing is mounted on the can. The bolt is introduced into its seat before the housing is applied to the can, and the can body prevents it from escaping when the housing is mounted upon said body. The housing has a seal aperture, 7", extending through from side to side across the bolt slideway near the outer end portion of said slideway, so that any customary-form. of fiat sheet metal seal introduced through said seal aperture, af ter the bolt has been moved to locking position, blocks the said bolt slideway and prevents the bolt from being Withdrawn until the seal has been first withdrawn. If preferred, instead of providing the housing with the seal aperture, such seal aperture may be made in the bolt andpositioned to be exposed at the aperture, 7", for the introdu-ction-of the al when the bolt is at looking position; (see Fig. fl.)

Because it is preferable or more convenient to mount the locking device, as shown, in position to have the bolt thrust through the flared portion of the can body for en.-

gagement with the inteiiorly-telescoped cover member; and because at this position, in order to keep the housing within the minimum dimensions, preferably so that it drawing movement,it might be possible to wedge v1t out of engagement and so re-' move the cover without unlocking it. In order to give this direct right-angle engagement, the bolt, thrust in in an inclined direction, as shown, has near its inner end an annular groove, 8, which in section radial to'the bolt, is substantially right-angular in form .so that the slope nearestthe end, which is the part which engages with v the shoulder, 10, of the cover member, eX-

tends at such engagement horizontally,- that is, directly across the path of withdrawing movement of the cover and the groove; 11, is formed in said cover member with its lower side which constitutes the shoulder, 10, in a plane substantially at right angles to the axis of the can or direction of the withdrawing movement of the -cover. When the bolt is thus formed, it will be seen that it could not be thrust into the groove unless if at the lowest closed position of the cover member, the shoulder, 10, were at the level of the lower side of the knob, 8 which results from forming the bolt in the manner described, because that knob at its full diameter must be able to pass the lower outer margin of the groove in entering the latter. It is preferable, therefore, to form the groove described in the bolt so that at the full in-thrust position of the bolt and lowest position of the" cover the said annular groove of the bolt at the lower side' of the latter stands entirely within the groove, and the periphery of the; shoulder, 10, is touched by the bolt at a point onthe latter a little back of said annular groove of the bolt, as seen in Fig. 3. With the parts thus constructed, it will be seen that any attempt to withdraw the cover without having released the bolt mightpossibly cause the outer periphery of the shoulder, 10, operating on the inclined under surface of the bolt, to wedge the body member and cover member of the can apart at this point sufficiently to admit the said margin of the shoulder, 10, up into the right-angled annular groove of the bolt, the cover being withdrawn to the extent of the vertical depth of said annular groove, which wouldbe unobjectionable, since it would not amount to opening the can; but at this point the shoulder, 10, would abut squarely against the inner shoulder of the knob madeat the point at which the latter extends horizontally, and further withdrawing movement of the cover would have no tend ency to either crowd or wedge the bolt back, or the body and cover members of the can. apart.

In Fig. 5, there is shown a modification in which the lock is mounted wholly on the cylindrical and telescoped portion of the outer member and engages the cylindrical and interiorly telescoped portion of the inner member. 'In this form, the engaging bolt member is in the form of a hook, 15, positioned vertically, pivoted at its lower end in the housing, and having at its upper end a hook lip, 15, projecting inward through an aperture in the Wall of the outer member for engaging an upwardly facing shoulder, 16, formed on the inner member, preferably by rolling a circumferentially-extending groove, 16 into the outer surface of said outer member. A flat spring, 15", is preferably provided mounted in the housing and operating on the hook bolt to retract its hook lip outof engagement with the inner can member. The housing, 17, mounted, as stated, upon the cylindrical portion of the outer member of the can, has for so mount ing it two pairs of parallel vertically-extending flanges or feet, 17, which seat upon the vertical outer wall of said can member, leaving free vertical clearance between them from the aperture through which the lip, 15

protrudes for locking downward, so that there is no opportunity for the accumulation of dirt at or around the aperture which would not be readily flushed off in cleansing the can. In this vertical clearance space, 17 the hook bolt, 15, is located. In the housing, there is formed a slide path, 18, for a flat seal, 19, which slide path opens back of the of the pivoted hook bolt, 15, and when the flat seal bolt, 19, is in position in this slide path, it extends into the clearance space, 17, and presents an edge or side in that space at position for holding the seal bolt in its locked position; that is, with its lip, 15*, engaged with the shoulder, 16, of the inner can member. Transverse to the slide path of the seal, 19, the housing has an aperture, 20, which extends entirely across or through said slide path of the seal, and the seal has a tongue,

members being flared outwardly at the up-. J per part, in combination with said members,

be broken off by any attemptto putait in a position to permit the withdrawal of the seal. I Y
